Jeu de paume was a precursor to modern tennis that originated in France in the 12th century. It was played indoors without racquets but they were later introduced. Lawn tennis developed from jeu de paume and other sports, with two key innovations - in 1859 Major Harry Gem mixed different sports rules and equipment, and in 1873 Major Walter Clopton Wingfield designed and patented a similar game called Sphairistikè. Tennis basically consists of hitting the ball over the net to the opponent's side in singles or doubles play, following a scoring system of 15, 30, 40, and sets of 6 games.
